How many meters in 48 725 Cm?

Answer 1

I presume you mean cm as in centimeters (there being no C prefix in SI units):

100 cm = 1 m

⇒ 48725 cm = 48725 ÷ 100 m

= 487.25 m

I may seem picky over Cm and cm, but consider:

millimeters are mm; 1000 mm = 1 m

megameters are Mm; 1000000 m = 1 Mm

⇒ 1 Mm = 1000000000 mm = 109 mm

⇒ 1 mm = 0.000000001 Mm = 10-9 Mm

A difference of a factor of a billion made by the prefix being upper case (M) or lower case (m)!

It is important to write units in the correct abbreviation so that others read what you mean.
